Hi, My Girlfriend Had A Fever Blister On The Corner

Hi, my girlfriend had a fever blister on the corner of my mouth a couples weeks ago. And we had sex a few days ago. And now I've had a painful clitoris for several days and this morning I applied pressure to it and white discharge came out of two sores on the bottom of my clitoris. Is this something serious? Can I put neosporin on it to help it heal faster? Since her fever blister was gone, we didn't think it would effect me.
